DNA-damage test could aid drug development
... an established cell-culture system based on mouse fetal
liver cells to create a new system based on adult red cell precursors from mouse bone marrow. Shuga patiently optimized the system, which allows the precursor cells to proliferate and differentiate in the normal way, dividing four or five times befor...

mortality rate overall and a higher proportion of male fetuses that die. “These results are not...
3-D ultrasound identifies women at risk for impending preterm birth
...th, 3-D ultrasound was used to measure the size of fetal

adrenal gland at the time a woman is evaluated for symptoms of preterm labor, may have major benefic...
First-degree fetal heart block may be reversible
There is an increased risk of fetal

heart problems. They also explored whether early treatment would reverse the problems. The team ...
Penn researchers replace organ in adult mice using 'single-parent' stem cells
...ertilized egg. The researchers could then harvest fetal
liver cell precursors for transplant. Ultimately, the scientists found that uniparental cells, regardless of parent of origin, were able to functionally replenish the entire blood-producing system of adult mice. The scientists were able to mai...
Statin plus cancer drug deliver combo punch to brain cancer cells
...0s, cyclopamine is a powerful toxin known to stunt fetal
development and cause birth defects in humans and animals. Its connection to anti-cancer efforts grew out of later insights into its blockage of hedgehog, which gets its name from spiky hairs that develop on fruit flies lacking the signal. "We alr...
Experimental vaccine given during pregnancy reduces stillbirths from common virus
...oss in newborn children who were infected in early fetal
life. Estimates place the number of U.S. children born with CMV each year at about 40,000, and there is no vaccine or treatment for pregnant women who have the infection. In a 2000 report, the Institute of Medicine of the National Academy of Scienc...

Stem cell therapy shows promise for rescuing deteriorating vision
...n rats, neural progenitor cells derived from human fetal
stem cells have been shown to protect the vision of animals with degenerative eye disease similar to the kinds of diseases that afflict humans. The new study appears today (March 28) in the journal Public Library of Science (PLoS) One. The lead au...
A potential biological cause for sudden infant death syndrome
...the abnormalities they observed begin during early fetal
development, and that prenatal insults like maternal smoking and alcohol use may adversely affect development of the brainstem serotonin system during this time. More research is needed to explain what causes the abnormalities and how they can be pr...
U of MN researchers turn cord blood into lung cells
...otherapy. Type II alveolar cells develop late in fetal
development, which is why some premature babies are born with underdeveloped lungs. The cells and the air sacs as a whole continue to mature and develop through a child's first few years of life. Now the researchers will try to better characteriz...
A silent pandemic: Industrial chemicals are impairing the brain development of children worldwide
...manent consequences. That vulnerability lasts from fetal
development through infancy and childhood to adolescence. Research has shown that environmental toxicants, such as lead or mercury, at low levels of exposure can have subclinical effects--not clinically visible, but still important adverse effects, s...
Detailed 3-D image catches a key regulator of neural stem cell differentiation in action
...ve us a lot of insight into the development of the fetal

Research links 'ecstasy' to survival of key movement-related cells in brain
...the survival of dopamine cells in the brain during fetal
development. Because these cells are critical in the regulation of voluntary movement, the findings, the researchers say, may lead to better therapies for neurological diseases like Parkinson's. Led by Jack Lipton, PhD, professor of psychiatry, ...
Technology for monitoring fetal oxygen during labor offers no apparent benefit
